Reaction of Methyl 2-Arylethylcarbamates with Thionyl Chloride: Formation of Benzothiazine and Benzo[b]thiophene Ring Systems
摘要:
The reaction of methyl 2-arylethylcarbamates with thionyl chloride induced a sulfur mediated ring closure to form benzothiazine and benzo[b]thiophene ring systems with concomitant chlorination of the aromatic ring.
